需要在Visual Studio 2017中从angular2验证angular4 [英] need to verify angular4 from angular2 in visual studio 2017

问题描述

我已将源代码从Angularjs2升级到Angularjs4.

I have upgraded my source from Angularjs2 to Angularjs4.

我正在使用Visual Studio 2017和ASP.NET MVC Core.

I am using Visual studio 2017 and ASP.NET MVC Core.

我现在想验证我是否正在使用更新的版本(4)或上一个版本(2).

I want to verify now either i am using the updated version (4) or previous one (2).

这是我的package.json

here is my package.json

   {
  "name": "angular-quickstart",
  "version": "1.0.0",
  "description": "QuickStart package.json from the documentation, supplemented with testing support",
  "scripts": {
    "build": "tsc -p src/",
    "build:watch": "tsc -p src/ -w",
    "build:e2e": "tsc -p e2e/",
    "serve": "lite-server -c=bs-config.json",
    "serve:e2e": "lite-server -c=bs-config.e2e.json",
    "prestart": "npm run build",
    "start": "concurrently \"npm run build:watch\" \"npm run serve\"",
    "pree2e": "npm run build:e2e",
    "e2e": "concurrently \"npm run serve:e2e\" \"npm run protractor\" --kill-others --success first",
    "preprotractor": "webdriver-manager update",
    "protractor": "protractor protractor.config.js",
    "pretest": "npm run build",
    "test": "concurrently \"npm run build:watch\" \"karma start karma.conf.js\"",
    "pretest:once": "npm run build",
    "test:once": "karma start karma.conf.js --single-run",
    "lint": "tslint ./src/**/*.ts -t verbose"
  },
  "keywords": [],
  "author": "",
  "license": "MIT",
  "dependencies": {
    "@angular/common": "~4.0.0",
    "@angular/compiler": "~4.0.0",
    "@angular/core": "~4.0.0",
    "@angular/forms": "~4.0.0",
    "@angular/http": "~4.0.0",
    "@angular/platform-browser": "~4.0.0",
    "@angular/platform-browser-dynamic": "~4.0.0",
    "@angular/router": "~4.0.0",

    "angular-in-memory-web-api": "~0.3.0",
    "systemjs": "0.19.40",
    "core-js": "^2.4.1",
    "rxjs": "5.0.1",
    "zone.js": "^0.8.4"
  },
  "devDependencies": {
    "concurrently": "^3.2.0",
    "lite-server": "^2.2.2",
    "typescript": "~2.1.0",

    "canonical-path": "0.0.2",
    "tslint": "^3.15.1",
    "lodash": "^4.16.4",
    "jasmine-core": "~2.4.1",
    "karma": "^1.3.0",
    "karma-chrome-launcher": "^2.0.0",
    "karma-cli": "^1.0.1",
    "karma-jasmine": "^1.0.2",
    "karma-jasmine-html-reporter": "^0.2.2",
    "protractor": "~4.0.14",
    "rimraf": "^2.5.4",

    "@types/node": "^6.0.46",
    "@types/jasmine": "2.5.36"
  },
  "repository": {}
}

，然后我通过程序包管理器还原了.

and then i restored through package manager.

我是否必须升级tsconfig.js和任何其他文件中的内容?

will i have to upgrade something in tsconfig.js and any other file(s) ?

推荐答案

转到您的项目文件夹的以下路径:

Follow to this path to your project folder :

node_modules -> @angular -> core -> package.json

然后在该文件上检查"_id"，例如:

then check for "_id" on that file, for example :

"_id": "@angular/core@4.1.3"

最后的版本号是您的实际棱角版本.

the version number at end is your actual angular version.
